The 6-point difference between high-end and low-end insertion force testing machines is significant in the market. High-end models offer superior performance, mid-range options provide a balanced choice, while low-cost alternatives often leave customers confused when making a purchase decision. As the first domestic manufacturer to independently develop and produce insertion force testing machines, we have gathered extensive market feedback and summarized the key features of our devices. Ultimately, the choice of which grade to purchase depends on the customer's company strength, test requirements, and intended use.
1. **Sensor Protection**: Our plug-in force testers are equipped with anti-collision protection. This feature allows for automatic testing, where the machine can be manually operated by pressing up and down keys multiple times to simulate collisions between the upper and lower fixtures. If the machine can automatically stop upon collision, it ensures better sensor protection, reducing operational worries and maintenance costs for the user.
2. **Test Speed Verification**: To verify the accuracy of the machine’s speed, set the maximum speed and stroke, then use a stopwatch and ruler to check if the actual speed matches the displayed value. If the supplier cannot provide accurate speed, it raises concerns about the quality of the machine and the integrity of the supplier.
3. **Password Protection on Verification Screen**: If the verification screen requires a password, it indicates that the machine can only be serviced or modified by the original supplier, leaving the customer at a disadvantage in future operations and pricing.
4. **Software Development Capability**: Check whether the software is developed in-house. Ask for minor customizations, such as converting mm/min to cycles per minute on the display. Low-cost models often use pre-designed templates with no flexibility. If the supplier lacks independent software development capabilities, it may indicate limited technical strength and potentially higher after-sales costs.
5. **Testing Functions**: High-end insertion force testing machines not only measure insertion force but also include advanced functions like break force testing (which can replace some tension machine functions), longitudinal connector force measurement, constant tensile pressure testing (commonly known as "hanging weight" test), and constant tension retention life testing.
6. **Stroke Adjustment Resolution**: The finest manual adjustment should be 0.01mm. You can manually click the controls to see if the movement is smooth and accurate. Many low-end models lack this precision, making them unreliable for critical applications.
In summary, low-end insertion force testing machines fall short in terms of supplier capability, technical expertise, integrity, and overall functionality compared to high-end models. Some third-party certifications exist, but simply checking the force value is not enough. It’s also important to evaluate the test speed and data connectivity between the hardware and computer. Machines with only basic interfaces like USB or RS232 are typically low-end, with limited sampling rates and delayed load protection.
